Ko & Martin is a boutique language service group that offers a broad variety of language services. We provide high caliber litigation support in interpretation and translation for Korean and Chinese languages. We are certified court interpreters for trials, depositions, arbitrations, mediations, witness preparations, attorney-client consultation, and provide certified translation of documents. We are also highly-qualified simultaneous conference interpreters for business conferences, symposiums, entertainment, and media events, etc. From small business disputes to complex intellectual property litigations, Ko & Martin is confident to meet all your language needs. Let us be a part of your team!


Without hesitation I can say that Ms. Ko is the most talented professional Korean interpreter and translator that I have had the pleasure to retain. Intellectual property litigation is often fraught with extremely technical terminology that generally presents issues for foreign interpreters and translators. Ms. Ko’s vast vocabulary and familiarity with technical terminology have consistently permitted her to excel with precision and accuracy in interpretation and translation. As a result of her friendly demeanor and great personality, working with Ms. Ko is also a pleasure. In short, Ms. Ko has a proven track record in highly technical litigations and she is always my first choice for any Korean interpreter or translator needs.

I have retained Ms. Martin for translation and interpretation services in numerous high stake lawsuits ranging from commercial cases in the Complex Litigation Department of California State Court, to hi-tech patent infringement action in the federal district court, and Section 337 investigation in the U.S. International Trade Commission (ITC). My clients and I have always appreciated her superb language skills, high-standard professionalism, and warm personality and will recommend her services to anyone in need without reservations.
